Answer:

Just divide to find that the percent increase is #20%#.

Explanation:

To find the percent increase, take the value you end with, and divide it by the number you started with.

In this example:

#(54"m")/(45"m")#

You can cancel the units:

#(54color(red)(cancel("m")))/(45color(red)(cancel("m")))#

#54/45=6/5=1.2#

Finally, convert #1.2# into a percent:

#1.2=120%#

As you started with #100%#, subtract that to find your percent increase.

#120%-100%=color(red)(20%#
